Mammut MTR 141 Half Zip Shirt Men's

It might be a touch early in the season to start your trail runs, but you can't wait another day, so you pull the Mammut Men's MTR 141 Half Zip Shirt over your head, lace up your shoes, and take to the dirt tracks. Despite the lingering snow in the shadows, this performance top keeps you comfortable in cooler conditions. Cooling panels under the arms and a half zip design enhance ventilation, so you won't work up a sweat and get chilled before you're done with your run.
